4、Performance TC6020A is a self-climbing tower crane with an upper slewing mechanism, a trolley mechanism

and a horizontal jib with two shackles. It is optimal designed by Changsha Changsha China National

Quality Supervision & Test Center for Construction & Urban-Building Machinery, which is the

technology authority organization of tower crane field in China, manufactured by "Zoomlion", strictly

supervised and proof-tested by. Its performances are advanced in China; many of them are advanced in

the world.

4.1 The performance of the whole crane

The performance specifications of the equipment include rated-hoisting moment, max working

radius, max hoisting capacity, max height of hoisting and working speed. The specifications are the

important indicator of the capacity and the efficiency of the tower crane. The concrete specifications

are shown as following "Main Specifications".

4.2 Working mechanisms

The performance of hoisting mechanism, slewing mechanism, trolleying mechanism and

traveling mechanism directly affects the whole performance of the tower crane. Users hope that the

crane is stable and reliable in working. The main factor influenced the stability of the crane is inertial

impact and electric current impact. "Zoomlion" has solved those knotty problems with advanced

technology in the TC6020A tower crane.

4.2.1 Hoisting mechanism

The hoisting mechanism of the TC6020A tower crane is designed to lift 10 tons.

The routine hoisting mechanism lifting 10 tons is adopted the special motor and

single-velocity-ratio spur gear reducer. The special motor with two-speed coiling rotor is braked by

eddy to regulate the speed.

Versus to the others velocity modulation modes, the motor with coiling rotor, braked by eddy,

acquires better performance with series resistors, starts and brakes smoothly. Shifters are switched over

smoothly. Fill its shoes correctly with slow speed, but it is forbidden to run long time under slow

speed.

Using the velocity modulation modes, it is very outstanding to reduce inertial

17


impact, prolong the lifetime of the components of the electrical control, prolong the

lifetime of the wire rope, and ensure that the mechanism has better stability and long

lifetime.

Using the special motor and single-velocity-ratio spur gear reducer, the mechanism has simple

structure, high reliability and easy maintenance.

Adopting the technology of big strong drum with LEBUS groove, it is very useful to solve the

knotty problem of abnormal orders when the wire rope is arranged on the drum.

According to the demands of users, the technology of frequency altering and stepless speed

regulated is adopted in hoisting mechanism, it is very useful to improve the running stability,

raise the accuracy of filling its shoes, reduce impact to electric network, simplify

the operation.

4.2.2 Slewing mechanism

As opposed to other mechanisms, the inertial impact of the slewing mechanism has

the most effect to the crane. The more the jib is long, the more effect is outstanding.

It can’t solve the knotty problem with the traditional slewing mechanism, which brings

about big torsional pendulum impact on the crane. After the motor being powered off,

the jib runs for a long time before stopping, lead to difficultly fill its shoes and

damage the slewing reducer.

The unique technology of frequency altering and stepless speed regulated is adopted

in the routine slewing mechanism of "Zoomlion" tower cranes at first in the world. Using

the slewing eddy controller, which "Zoomlion" owns the intellectual property, and

technology of frequency altering and stepless speed regulated, the slewing mechanism

starts and stops smoothly, fills its shoes fast and correctly.

4.2.3 Trolleying mechanism

The trolleying mechanism, which affects the load filling its shoes, is important

mechanism. Using the technology of frequency altering and stepless speed regulated,

the speed of the trolley changes in the range of 0～55m/min, it is very efficient to

reduce the running impact and improve the operating stability and working efficiency

in TC6020A.

18


4.2.4 Traveling mechanism

A planetary reducer and the technology of frequency altering and stepless speed

regulated are adopted in the traveling mechanism. The speed of the traveling mechanism

changes in the range of 0～25m/min smoothly without impact.

The motor connects with the planetary reducer, and then connects with the wheel. The

mechanism has high reliability and following advantages: the structure is simple, the weight is light,

the volume is small, and the figure is good-looking.

4.3 Electrical control system

Adopt PLC in electrical control system to improve reliability and safety. Using

PLC (programmable logic controller) as the main control unit, it is very useful to reduce

the quantity of logic control components, decrease the failure rate of the control system,

and improve the reliability. The system controls the three mechanisms (Hoisting

mechanism, Slewing mechanism and Trolleying mechanism) together, collects all the

safety-limit signals, and deals with those signals in complicated logic, it is very

efficient to optimize the mechanisms motion and avoid false operation. The system can

self-diagnose electric faults and give corresponding alarms with different sounds and

lights.

The main electric elements are used world-renowned products, it is the key of high reliability of

"Zoomlion" tower crane, such as contactor and circuit-breaker of France Schneider, PLC

controller of Japan Mistubishi Companies, and frequency converter of Japan

Yaskawa Electric Corporation. Those components have over load capacity and

stable performance.

In general, the electric fault occupies 70% of all tower crane faults. However, "Zoomlion" tower

cranes have fewer faults than others tower cranes, because of advantage of electric system design,

fitness parameter of special motor, small impact, world-renowned electric components, and correct use

of customers.

4.4 Safety-protection device

According to GB5144 safety regulation of tower crane, "Zoomlion" tower cranes are equipped

with safety-protection devices such as moment limiter, overload limit switch, over hoist limit switch,

19


slewing limit switch, trolley limit switch and anemoscope. In addition, "Zoomlion" tower cranes are

equipped with many devices, which are advanced or original created by "Zoomlion" such as automatic

hook rate-changed device, original created double-tensile devices of trolley wire rope, trip-proof device

of climbing, fast-hitch connectors fixed the slewing mast and jib or counter-jib. All these devices

ensure the tower cranes safety and usage facility.

4.5 Structure

By means of optimal design, computer-aided design, three dimensions Pro/E design, modularity

design and manufacture, electro-mechanical integration design, man-machine engineering design,

Ideas or Adams engineering analyzing, the structure of "Zoomlion" tower crane has gradely strength,

stiffness, fatigue failure resistance and well overall performance.

Using special square shaped steel tube in the main stand bars and belly bars of the "Zoomlion"

TC6020A tower crane, it is attractive in appearance, good mechanics performance, simple welding

technology, high reliability, and more reasonable than seamless steel pipe or angle steel. The square

shaped steel tube structure has following advantages: small wind resistance, good stiffness. Using

shielded arc welding, it is useful to assure the welding quality, and good-looking welded seam.
